Abstract

Washing clothes and other activities can not be separated from the use of detergent. In the detergent there is a phosphate content contained in the builder. Excessive use of phosphate substances can disrupt the balance of the ecosystem in water which causes eutrophication. Based on Government Regulation of the Republic of Indonesia No. 18 of 2001 concerning Water Quality Management and Water Pollution Control that the minimum phosphate content produced from the waste of a business activity which is classified as class 2 is 0.2 mg/liter. To reduce the phosphate content in laundry waste, bioadsorbents from banana stem charcoal can be utilized. For this reason, the purpose of this study was to determine the absorption, time and optimum stirring of banana stem bioadsorbent in absorbing phosphate content in laundry waste and to determine the decrease in phosphate levels with banana stem bio-adsorbent according to the quality standard of Government Regulation. The method used is adsorption by varying the mass of the adsorbent (1, 3 and 5 grams), contact time (40, 60 and 80 minutes) and stirring (150, 300 and 600 rpm). There are several stages, namely activation of banana stem bioadsorbent with NaOH, preparation of laundry waste samples, measurement of phosphate levels in laundry waste before adding bioadsorbent with KH2PO4 standard solution using a UV-Vis spectrophotometer and testing the adsorption capacity of bioadsorbents in laundry waste. The adsorption carried out was obtained at variations in contact time, namely at 80 minutes the adsorbed phosphate concentration was 3 mg/L with a percentage of 9% adsorbed waste, then the mass variation obtained a mass of 5 grams with an adsorbed phosphate concentration value of 20 mg/L with a percentage of 67%. and variations in the speed of the stirrer obtained at 600 rpm the value of the adsorbed phosphate concentration of 25 mg/L the percentage of adsorbed waste was 80%.

Additional Information: Kegiatan mencuci pakaian dan lainnya tidak akan terlepas dari penggunaan detergen. Dalam detergen terdapat kandungan fosfat yang terdapat dalam builder. Pengguaan zat Fosfat yang berlebih dapat mengganggu keseimbangan ekosistem pada air yang menyebabkan eutrofikasi. Berdasarkan Peraturan Pemerintah Republik Indonesia No. 18 Tahun 2001 Tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air bahwa minimal kandungan fosfat yang dihasilkan dari limbah suatu kegiatan usaha yang termasuk kelas 2 yaitu sebanyak 0,2 mg/liter. Untuk menurunkan kandungan fosfat dalam limbah laundry dapat memanfaatkan bioadsorben dari arang batang pisang. Untuk itu, tujuan dari penelitian ini adalah mengetahui daya serap, waktu serta pengadukan optimum bioadsorben batang pisang dalam menyerap kandungan fosfat pada limbah laundry serta mengetahui penurunan kadar fosfat dengan biodasorben batang pisang sesuai baku mutu Peraturan Pemerintah. Metode yang digunakan yaitu adsorpsi dengan memvariasikan massa adsorben (1, 3 dan 5 gram), waktu kontak (40, 60 dan 80 menit) dan pengadukan (150, 300 dan 600 rpm). Terdapat beberapa tahapan yaitu aktivasi bioadsorben batang pisang dengan NaOH, preparasi sampel limbah laundry, pengukuran kadar fosfat limbah laundry sebelum ditambahkan bioadsorben dengan larutan standar KH2PO4 menggunakan spektrofotometer Uv-Vis dan Pengujian daya jerap bioadsorben pada limbah laundry. Penjerapan yang dilakukan didapatkan pada variasi waktu kontak yaitu pada waktu 80 menit konsentrasi fosfat teradsorpsi sebesar 3 mg/L dengan persentase limbah teradsorpsi 9 %, kemudian pada variasi massa didapatkan massa yaitu 5 gram dengan nilai kosentrasi fosfat teradsorpsi sebesar 20 mg/L persentase 67 % dan variasi kecepatan pengaduk didapatkan pada pengaadukan 600 rpm nilai konsentrasi fosfat teradsorpsi sebesar 25 mg/L persentase limbah teradsorpsi yaitu 80 %.
